Very handy rig, easy to handle, can do just about one can imagine, battery charge lasts, very clear display, easily interfaced to a laptop or PC, very useful measuring tool for electronics and antenna frequency matching.

My first unit has a non-functioning touch screen. I returned it and the replacement worked. This revised review is for the working unit.This is a very potent unit which can to lots of things.The downsides are it does not work well below 50kHz (although the description says 10kH--the actual spec is 50kHz). The unit has some jitter even after calibration. The feature to lock the trace is helpful while taking measurements or screen shots because of that. The battery life seems short if you are doing a bunch of measurements. You will want to charge it every time. The hole in the case to get to the micro-SD card slot is sloppy. The first time I tried to re-insert the SD card it missed the slot and ended up loose inside the unit and I had to disassemble it using the 4 screws in back to get the SD card out. Also the SD card is not hot swappable. Mine crashed if I removed the card. You will have to turn the unit off and have to reconfigure your session if you want to get data or screen shots to a computer. Probably better to install the Windows software and control the unit from the PC over USB.Overall I am happy with the purchase.

It works great and measures everything, even cable length, cable loss, swr, and resonant frequencies of the antenna. Fits in the palm of your hand. Be sure and order cable connector adapters and patch cables. There are no instructions, so, watch YouTube videos on how to operate.

I have read a little on these devices over the past few months, and decided that for ham radio use, if they worked as well as people seemed to think, the small size, internal battery etc. would make it ideal for field antenna work.I really wasn't expecting that much at this price. However, it arrived in a nice looking box with fitted internal compartments for cables, connectors etc.My first quick play with it impressed me. I was suspicious about using a square-wave and using harmonics for the higher ranges, but if you forgive the reduced measurement range, that actually works pretty well. Not as well as my bench VNA, but that cost just a tiny bit more. The biggest potential problem is the number of sample points. Being fixed at 101 points is rather limiting for wide-band scans. That said, its not that usual outside of microwave use that wide bandwidth scans are used/useful. If you really need that, there is software available (free) for Windows and Mac to control the nanoVNA, and with the ability to split the range into some number (you decide - how long you want to wait) of segments, and scan each segment individually, merging the results into a single view.If I had to find fault, it would pretty much be with the external components:* A guitar pick is better than a finger on that little screen, but a stylus would be better.* There is only one 50ohm load, the proper calibration procedure requires two, although you *can* use just one.* The open and short calibration loads are identical once connected or an adapter fitted. Marking these 'O' and 'S' would be useful.* The box is too nice to toss away, but lacks space for additional adapters/connectors.All that said, I highly recommend this for anyone wanting a VNA for sub-microwave use and not requiring ultra-precision. If you have never used this sort of equipment before there is a somewhat steep learning curve, and most documentation is either at too high a level for a lot of people, and assuming lots of basic knowledge, or really too low level and created by people that are maybe not really grasping what they are doing. I expect that problem to resolve fairly quickly.As an antenna analyzer for ham radio use it blows most of those costing 10 or more times as much out of the water, and is useful for other things too (like tuning filters etc.).only using for SWR across multiple bands, but beats the price on buying multiple meters.

I was a little sceptical about this device but it has exceeded all expectations, a little tricky to navigate the menu structure (use the supplied cheat sheet and it's a breeze), otherwise it's a great tool with an easy to read display.The only critical comment I can make is about the charging cable, it's a very cheap usb-c cable and doesn't work one way round, I use a higher quality cable and have no problems with it.

I bought the nanoVNA in order to tune a new 20-meter dipole antenna that I was installing. The antenna is the Radiowavz 20-DP11 with 1:1 balun. I was able to buy the preassembled antenna for about the same as it would have cost to buy the center insulator/balun and the #14 AWG copper clad steel antenna wire. It is a very well constructed antenna. Anyway - back to the nanaVNA - I got the antenna up about 40 to 50 feet in some big trees in my yard and took the first reading with the nanoVNA. My goal was to tune it for lowest SWR at 14.250 MHertz - the center SSB phone section of the 20-meter band. I built an Excel spreadsheet to calculate frequency vs. antenna leg length with an assumed velocity factor of 0.98. My first reading on the nanoVNA indicated that each leg was about 10-inches too long. I lowered the antenna and reduced each leg by about 8-inches - not by cutting them - but by twisting them back over the leg of the antenna. My second reading on the nanoVNA indicated that I was still about an inch too long so I lowered the antenna and folded back another inch. This time it read spot on with the lowest SWR of 1.28 at exactly 14.250-MHertz. So, lowered the antenna again and cut off several inches, twisted the rest back over the leg, secured with a couple of wire tires and taped it up good. I came back into the shack, fired up the rig and immediately contacted Italy, Bulgaria and Azores with a 59 signal report. I don't have an amplifier and only run 100-watts barefoot but I consistently get signal reports where the the contact is surprised that I'm not running 1000-watts into a beam antenna. The antenna works great across the entire 20-meter phone band and I have been surprised and delighted with the difference that a finely tuned resonant antenna makes vs a compromise antenna like my 160-meter G5RV. The nanoVNA apparently was spot on with helping me find the right length of my antenna. I decided to try this before in vesting in a $300 or $400 antenna analyzer and I'm glad I did. FYI - there is an excellent user manual available for the nanoVNA on the nanoVNA group on the groups.io conference board. 73 - K4IXO
